Hi,

If you are using database connection for combobox filling then

Do coding on category.SelectedIndexChanged. When selected gets changed then pass that index or selected value to database and fetch items related to that category and bind it to the second combobox. Use Property called Selectedvalue or SelectedIndex to retrive current selection of a category

What you are referring to is "Cascading Dropwdowns".

See this link to an example http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx[^]

At the bottom of the link, there is another link to an example which uses a database for the data source.

Hope this helps.

Hi
Firstly Load database value to combobox category on form load event then double click on category combobox to get the event which is selected index change in this pass where query to the database and selected data load to new combobox which is items combobox in C#

I have tested this code is run successfully on my computer.
